The following initial assessments will occur prior to receiving the RSWT or placebo: At SJCG: participants will undergo quantitative sensory testing for allodynia and hyperalgesia by one of the physicians. At Lakehead University School of Kinesiology: participants will have basic demographic information such as height, weight and age, measured and recorded on a data abstraction form by a member of the research team. The participant will also be asked to consider the most painful spot within each of the 3 most painful regions in his/her body. Participants will mark on a 100 millimeter VAS scale at the point that corresponds to the pain intensity for each region. The amount of pain will be estimated by measuring in millimeters the distance from the "no pain" marker to the mark provided by the participant for each question. This will be recorded on the data abstraction form. Pressure pain threshold will next be measured on the most painful spot within each of the 3 most painful regions using a Baseline© Pressure Tolerance Meter (60 lbs). Pressure will be applied perpendicular to the tissue in the three most painful regions as indicated by the participant. The participant will be asked to report when the pressure applied to the region became painful and the amount of pressure shall be recorded in pounds on the data abstraction form. A 30 second rest shall be allowed for recovery and the same technique shall be applied to the other painful locations. The specific location of the painful region shall be marked and documented by a trained member of the research team. Next, participants will be asked to complete the Beighton Scoring Screen for hypermobility, Beck's Depression Scale, and Pain Catastrophizing Scale questionnaires. All scores will be recorded on the data abstraction form. At Lakehead University (NOSM rooms 1002A, C, D E, F or School of Kinesiology SB-1028): participants will be scheduled to have a blood sample drawn by a registered phlebotomist. Specialized vacutainers will be used to isolate Peripheral Blood Mononuclear Cells (PBMCs) which will be later used in cytokine protein analysis. All blood taken will be labeled with a participant code to maintain confidentiality, and stored at NOSM.
